card-rates means that for different data rates the tx-power is calculated according to the cards transmit power algorithm from the cards eeprom and as an argument it takes tx-power value specified by the user.

default means that the card will use the tx-power values from the cards eeprom and will ignore the setting what is specified by the user in the tx-power field.

By default, this setting is set to default. TX-power-mode tells the wireless card which tx-power values should be used.

excessive power usage for the card and this may overload the 3.3V power supply of the board that the card is located on resulting in voltage drop and reboot or excessive temperatures for the board.

overdriving the amplifier which will cause more data errors.

overheating of the power amplifier chip and the card which will cause lower efficiency and more data errors.

Changing the default setting may help with some cards in some situations, but without testing, the most common result is the degradation of range and throughput. In general, tx-power controlling properties should be left at the default settings. If you want to use larger tx-power values, you are able to set them, but do it at your own risk, as it will probably damage your card eventually! Usually, one should use this parameter only to reduce the tx-power. The tx-power default setting is the maximum tx-power that the card can use and is taken from the cards eeprom. there will be no only-ack frames), then you can't compare frames to hw-frames as in case of regular wireless links. If there is traffic on both directions at maximum speed (eg. These ACK frames will not be added to the frames count, but they will appear at hw-frames. In the case of Nstreme, only the ACK can be transmitted in a single frame, if there is no other data to send. The frames counts only those which contain actual data. Can I compare frames with hw-frames also on Nstreme links? Some number of retransmissions is to be expected, but if the value of frames exceeds the value of frames multiple times, there is an issue with the wireless link that requires troubleshooting.

The number of retransmissions taking place can be determined by subtracting the value of the frames parameter from the value of the 'hw-frames parameter for a given entry in the registration table. Wireless retransmits increase the latency and lower the throughput of a wireless link. Wireless retransmission occur when an interface sends out a frame and doesn't receive back an acknowledgment (ACK), causing it to try sending the frame again until an acknowledgment is received or the maximum allowed retransmission count for a packet is reached. What are wireless retransmits and where to check them? Note that executing this command also disables the interface, so please be careful not to execute this command if you are configuring router remotely using that wireless link that you want to reset the configuration. In this case, you can use the reset-configuration command in the wireless menu - it will reset the all the wireless settings for the specific wireless interface and you will be able to configure the interface from the start.

Sometimes when you change some wireless setting for tuning the links you got so far that the link isn't establishing any more or works unstable and you don't remember what settings you had in the beginning.
